"At first I did feel sorry for him, and wondered if he would be able to have the quality of life my four- legged dogs have."

However, Pee-Wee managed to convince Patrice otherwise from the get-go: "That very first night he quickly changed my mind with his very first 'hop'."

Weighing a diminutive three pounds, Pee-Wee has continued to amaze and delight his owner

"Pee-Wee let me know despite him only having two legs, in his mind he wasn't disabled at all. He is such a character - he runs, hops, walks on two legs and he is super fast.

"He lifts himself up really well and has great balance. He is quite the little tenacious spitfire, but he has a very loving heart that is much bigger than his tiny Chihuahua body."

Patrice has had a set of wheels made for Pee-Wee "but they are a little hard for him to use because he needs more stabilisation, so I will be trying out a few different options for him in the near future.

Therefore for the moment Pee-Wee is getting by using his famous 'ninja-hop'.

The impact he's had on Patrice's life has been significant, and she has set-up a Facebook page - Pee-Wee's Playground - for him where he also touches the hearts of others.

"Pee-Wee provides hope and inspiration to thousands of people from all around the world where he shows that with courage, love and determination the word 'disability' does not mean inability.

"I receive messages on a daily basis about how Pee-Wee helps people to get through their own struggles in life. He can do anything dogs with four legs can do, he just does it a little differently.

"Pee-Wee believes in donating items to animal rescue auctions, sending care packages to animals in need and helping to get wheels for other disabled animals.

"His motto is: 'Never let adversity get in the way of your own happiness'."
